Rubble stone — fraction Бут of cubic-shaped diabase crushed stone from the Sartauskoye-8 deposit in Aktobe region. Manufactured by Heidelberg Kurylys Cement LLP (HKC) from rock with strength grade M1400, frost resistance F300, cubical grain shape and flakiness ≤10%.
DIABASE RUBBLE STONE (QUARRY STONE)
- Material
- Rubble stone, diabase
- Size
- Large blocks (150-500 mm and over, on request)
- Grade
- M1400 strength, F300 frost resistance, minimal water absorption
- Use
- Rubble masonry, gabions, shore reinforcement, landscaping
Diabase rubble stone consists of large blocks of hard igneous rock from the Sartauskoye-8 deposit. High M1400 strength, F300 frost resistance and minimal water absorption make the material resistant to heavy loads, aggressive water and freeze-thaw cycles. The angular, unrounded shape ensures reliable interlock in masonry and gabion structures.
Key applications: rubble masonry for foundations, retaining walls and buried structures where massive natural-stone bases are required; gabion mesh structures reinforcing slopes, embankments and retaining works; shore reinforcement — protection of riverbanks, reservoirs and port facilities against erosion; landscape compositions — alpine rockeries, rock gardens and decorative landscaping elements.
Logistics: rail shipments across Kazakhstan — Atyrau, Aktobe, Uralsk, Mangystau. Loading into the customer’s wagons or delivery to your station is available. Block size and batch volume are agreed individually per project. Submit a request and our managers will confirm lead times and delivered cost.

Frequently asked questions
How much does rubble stone (diabase) cost?
Retail price of rubble stone (diabase) at HKC is 3,500 KZT/t including VAT, with wagon loading at Bershogyr station included. Wholesale terms are available for large buyers — contact our manager.
What is the difference between cubic-shaped and ordinary crushed stone?
Cubical grain shape (flakiness ≤10%) produces tighter packing. In concrete this means lower cement consumption for the same strength grade — up to 10-15% saving. In asphalt, cubical aggregate delivers better bonding with bitumen and a longer pavement life.
What is the minimum order?
Minimum order — 1 rail wagon (about 69 tonnes). For large projects we assemble trains of any size. Truck shipping is not offered — rail only.
Which destinations do you serve?
We ship by rail across Kazakhstan from our siding at Bershogyr station (Shalkar district). Primary destinations: Atyrau, Mangystau (Aktau), Aktobe, Uralsk and other regions. Delivered prices on request.
Which documents are provided?
Every batch ships with a quality passport, test reports and conformity certificate per GOST 8267-93. Tender packs include a radiological report.
